Iniciar ou interromper um servidor SFTP

É possível interromper ou iniciar um servidor SFTP para gerenciar o estado dele, controlar o acesso e ajudar a otimizar os custos.

Interromper um servidor desativa o acesso e reduz o uso de recursos. Por exemplo, se você suspeitar de acesso não autorizado a um servidor, poderá interromper todas as transferências ativas e bloquear novas conexões interrompendo o servidor. Como outro exemplo, é possível reduzir os custos de tempo de atividade do servidor pausando um servidor durante períodos em que nenhuma transferência de dados é esperada.

Quando você inicia um servidor, o acesso é restaurado e os usuários podem se conectar a ele.

Funções exigidas

Para receber as permissões necessárias para iniciar ou interromper um servidor SFTP, peça ao administrador para conceder a você o papel do IAM de Administrador do Cloud FTP (roles/ftp.admin) no projeto. Para mais informações sobre a concessão de papéis, consulte Gerenciar o acesso a projetos, pastas e organizações.

Esse papel predefinido contém as permissões necessárias para iniciar ou interromper um servidor SFTP. Para acessar as permissões exatas necessárias, expanda a seção Permissões necessárias:

Permissões necessárias

As permissões a seguir são necessárias para iniciar ou interromper um servidor SFTP:

Inicie um servidor: ftp.servers.start
Interromper um servidor: ftp.servers.stop

Essas permissões também podem ser concedidas com funções personalizadas ou outros papéis predefinidos.

Interromper um servidor

Quando você interrompe um servidor, acontece o seguinte:

O acesso é negado e as conexões ativas são descartadas. Os usuários que têm uma conexão ativa podem ver uma mensagem de erro como esta:
```
Connection is terminated: Connection closed by remote host
client_loop: send disconnect: Broken pipe
Connection closed
```
Não é possível estabelecer novas conexões.

Para interromper um servidor, siga as etapas abaixo.

REST

Para interromper um servidor, use o método servers.stop.

Antes de usar os dados da solicitação abaixo, faça as substituições a seguir:

PROJECT_ID: o ID do projeto do Google Cloud servidor.
LOCATION_ID: o Google Cloud local do servidor, como us-west1.
SERVER_ID: o ID do servidor.

Método HTTP e URL:

POST https://ftp.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/servers/SERVER_ID:stop

Para enviar a solicitação, expanda uma destas opções:

curl (Linux, macOS ou Cloud Shell)

Observação: o comando a seguir pressupõe que você tenha feito login na CLI do gcloud com sua conta de usuário executando gcloud init ou gcloud auth login, ou usando o Cloud Shell, que faz login automaticamente na CLI gcloud. . Para saber qual é a conta ativa no momento, execute o comando gcloud auth list.

Execute o seguinte comando:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d "" \
     "https://ftp.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/servers/SERVER_ID:stop"

PowerShell (Windows)

Observação: o comando a seguir pressupõe que você tenha feito login na CLI gcloud com sua conta de usuário executando gcloud init ou gcloud auth login . Para saber qual é a conta ativa no momento, execute o comando gcloud auth list.

Execute o seguinte comando:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -Uri "https://ftp.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/servers/SERVER_ID:stop" | Select-Object -Expand Content
